​Network tomography allows us to infer internal characteristics, such as node and link properties (delay, jitter, packet drop, status), from end-to-end measurements. This talk will describe our recent work on deterministic and stochastic approaches to inferring link metrics that may be Boolean, or additive/multiplicative across the path. The talk will cover minimal monitor placement, path construction, identifiability and optimal probe allocation. My collaborators in this work include Liang Ma, Ting He, Chang Liu, Paul Yu, .Don Towsley and Kin Leung.


Ananthram Swami is with the US Army Research Laboratory and is the Army's Senior Research Scientist (ST) for Network Science. Prior to joining ARL, he held positions with Unocal Corporation, USC, CS-3 and Malgudi Systems. He was a Statistical Consultant to the California Lottery, developed a Matlab-based toolbox for non-Gaussian signal processing. He has held visiting faculty positions at INP, Toulouse., and currently at Imperial College. He received the B.Tech. degree from IIT-Bombay; the M.S. degree from Rice University, and the Ph.D. degree from the University of Southern California (USC), all in Electrical Engineering. Swami's work is in the broad area of network science, with emphasis on wireless communication networks. He is an ARL Fellow and a Fellow of the IEEE.
